Question

Max tossed a fair coin 3 times. What is the probability of getting heads in the first two trials and tails in the last trial?

Answer 1

1/8

Answer 2

No its not that

Answer 3

\[\text{probability} = \frac{ \text{number of favourable outcomes} }{ \text{number of possible outcomes} }\] and you should note it can never be greater than 1.

Answer 4

So if we flipped one coin for example, we would have \[\frac{ fav }{ pos } = \frac{ 1 }{ 2 } = 0.5 = 50 \%\]

Answer 5

thats the probability of getting heads if you flip one coin

Answer 6

So if you had two then we would have \[\frac{ fav }{ pos } = \frac{ 2 }{ 4 }\] see a patten here?

Answer 7

so does that mean with three it would be 3/12

Answer 8

oh wait maybe 3/8

Answer 9

but if that is true the teacher marked it wrong
